Abstract:

Taking five typical forest types in the Baihuashan National Nature Reserve as the research object,the litter accumulation and water holding characteristics of the five forest types in Baihuashan were quantitatively analyzed.And the results show that,among the litter accumulations of 5 types of forests in Baihua Mountain,Larix gmelinii(15.75 t/hm2)>Juglans mandshurica (9.99t/hm2)>Picea meyeri (10.27t/hm2)>Mongolia oak (7.34t/hm2)>Betula nigra (7.04t/hm2),the proportion of undissolved layer in litter layer of coniferous forest was significantly higher than that of broad-leaved forest;among the total water holding capacity of 5 forests in Baihua Mountain,Larix gmelinii(2.91mm)>Juglans mandshurica (2.77mm)>Betula nigra (1.90mm)>and Mongolia oak (1.83mm) >Picea meyeri (1.29mm);in the litter layer of coniferous forest,the water holding capacity of undissolved layer is greater than that of semi-decomposed layer,while in the litter layer of broad-leaved forest,the water holding capacity of semi-decomposed layer is greater than that of non-decomposed layer.The accumulation and hydrological effects of litter in the undissolved layer of coniferous forest were higher than those in the semi-decomposed layer,while those in the semi-decomposed layer of broad-leaved forest were higher than those in the undissolved layer.

Key words: Baihua mountain, typical forest types, litters, stock volume, water holding characteristics
